Hello,
There is something really strange, because when I connect to my MCC, I can see that accounts were actually created, although the API throws me a soap error.
For example, here is another Tracking ID error 772ff62a-c964-4338-9b18-f865131d6de6. And yet, an account was created (F110NPVB).
I didn't mentioned it in previous message, but I'm using PHP sdk with 13.0.17 version of the API.
Any ideas ?
